His vehicle then collided with the car on a road close to the royals'Sandringham private residence in Norfolk. He was taken to hospital for a precautionary check-up but was given the all-clear.

Both Ms Fairweather and the driver required treatment,but the nine-month-old baby escaped unharmed.

Just two days after the incident,Prince Philip was spotted behind the wheel once again - this time without a seatbelt.

Prince Philip's apology,in full:

“Dear Ms Fairweather,

I would like you to know how very sorry I am for my part in the accident at the Babingley cross-roads.

I have been across that crossing any number of times and I know very well the amount of traffic that uses that main road.

It was a bright sunny day and at about three in the afternoon,the sun was low over the Wash.

In other words,the sun was shining low over the main road. In normal conditions I would have no difficulty in seeing traffic coming from the Dersingham direction,but I can only imagine that I failed to see the car coming,and I am very contrite about the consequences.

I was somewhat shaken after the accident,but I was greatly relieved that none of you were seriously injured.

As a crowd was beginning to gather,I was advised to return to Sandringham House by a local police officer. I have since learned that you suffered a broken arm. I am deeply sorry about this injury.

I wish you a speedy recovery from a very distressing experience.

Yours sincerely,Philip"
